We're staying at the Wynn and Bellagio on our next trip, but also had an offer for 3 nights comped at the Venetian/Palazzo. Some friends of ours we'd very much like to meet up with just moved to So. Cal so I booked the "spare" offer at the Palazzo and will let them stay in the room. (I have every intention of playing some at the Palazzo, so I won't completely no-play them.) I know people do this all the time, but having never done so myself I'm getting curious about the details of how it works. Do I just give them the keys and let them have at it? I know the Palazzo checks room keys as you go to the elevator, but just to see if you have one - there's no way the guard would know if it's in your name or not. Or is it better (or even possible) to have one person of the couple listed on the room account? I'm thinking of them getting back to the room late to find the room key doesn't work, then they have to call me and have me come over to get a new key (not a huge problem, but I might be drunk off my a$$ at the time :evillaugh ). I do trust them not to take a bunch of stuff from the mini-bar. But then, if they wanted to could they order room service? Sorry for being a complete nube on this subject, but I know plenty of VMBers out there have lots of experience with this.
